Embodiment 1
[0027] Example 1, such as figure 1 Shown:
[0028] An improved Tan sheepskin tanning process, comprising the steps of:
[0029] S1: Soaking in water: Soak the Tan sheepskin in water to restore the Tan sheepskin to its fresh state;
[0030] S2: Meat scraping: use a round knife to remove the meat layer inside the Tan sheepskin, remove the meat and fat, and then use a degreasing agent to remove the oil film on the Tan sheepskin skin to facilitate the penetration of the tanning agent;
[0031] S3: Weighing: Weigh the Tan sheepskin after scraping the meat, and record the total weight;
[0032] S4: Tissue fixation: according to formaldehyde 30g / L, absolute ethanol 50g / L, 1-methyl-3-octylmethoxyimidazolium tetrafluoroborate 20g / L, phenol 15g / L, solvent is deionized water Prepare tissue fixation solution, the preparation process is: heat deionized water to 45-50°C on a water bath stirrer, then add formaldehyde, absolute ethanol, 1-methyl-3-octylmethoxy imidazole tetrafluoroborate ...

Abstract
The invention relates to the technical field of tibet lamb skin tanning, in particular to an improved tibet lamb skin tanning technology. The improved tibet lamb skin tanning technology comprises the following steps of 1, water immersion, 2, fleshing, 3, weighing, 4, texture fixing, 5, degreasing, 6, tanning, 7, rinsing, and 8, drying. The improved tibet lamb skin tanning technology is good in environmental protection effect, manufactured tibet lamb skin fur is bright and pure white, skin is full, light and soft, the properties such as oxidation resistance, reduction, acid and alkali resistance, anticorrosion, shrinkage temperature and dyeing are good, the problems of waste liquid non-effective processing, environment polluting, firm combining of a tanning agent and collagenous fibers and fur losing caused by adoption of a pure chrome tanning method and an aluminum tanning method can be avoided by using the composite tanning agent, and the good practical and promotion values are achieved.
Description
technical field [0001] The invention relates to the technical field of Tan sheepskin tanning, in particular to an improved Tan sheepskin tanning process. Background technique [0002] Tan sheepskin is one of my country's traditional export native products. It is well-known at home and abroad for its strong leather board, light weight and warmth, smooth and beautiful fur, and curved wave pattern. It is a unique animal husbandry resource in Ningxia. The existing Tan sheepskin tanning process mainly contains following several, namely chrome tanning method and aluminum tanning method. The chrome tanning method has low skin yield, thick skin, easy to shed hair and produces a large amount of chrome tanning waste liquid, which cannot be effectively treated and pollutes the environment; the aluminum tanning method has the problem that the combination of aluminum salt and collagen fibers is not firm Phenomenon. Therefore be necessary to provide a kind of new Tan sheepskin tanning p...
